Office 365 Admins and MFA - Restrict to use App only, not allow SMS or voice?
Hi, I'm wondering if it's possible in Office 365 w. E3 licence to setup MFA for Admins so the only authentication method they can use is app only (e.g. Azure Authenticator), not SMS or voice. All othe...
Nope. You can disable specific methods, but the configuration will indeed apply to all users.
Where is the setting found to restrict globally to mobile app? I don't want to involve SMS text messages or phone calls.
- Never mind... I found it here:

- Hi Vasil, thanks for confirming. Is there any 2FA solution you could recommend trying? Thanks again,
The Server (on-premises) version of Azure MFA allows you to configure the default method for each user, so if you block all others the will only be able to use the app. However, the block settings will again apply to all users.
